Jean Victoire Audouin
Jean Victor Audouin (27 April 1797 – 9 November 1841), sometimes Victor Audouin, was a French natural history, naturalist, an entomologist, Herpetology, herpetologist, ornithologist, and malacologist. Biography Audouin was born in Paris and was educated in the field of medicine. In 1824 he was appointed assistant to Pierre André Latreille, professor of entomology at the Muséum National d'Histoire Naturelle, where in 1833 he became Latreille's successor. In 1838 he became a member of the French Academy of Sciences. His principal work, ''Histoire des insectes nuisibles à la vigne'' (1842), was completed after his death by Henri Milne-Edwards and Émile Blanchard. Many of his papers appeared in the ''Annales des sciences naturelles'', which, with Adolphe Theodore Brongniart and Jean-Baptiste Dumas, he founded in 1824, as well as in the proceedings of the Société entomologique de France, of which he was one of the founders in 1832.

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Émile Blanchard
Charles Émile Blanchard (6 March 1819 – 11 February 1900) was a French zoologist and entomologist. Career Blanchard was born in Paris. His father was an artist and naturalist and Émile began natural history very early in life. When he was 14 years old, Jean Victoire Audouin (1797—1841), allowed him access to the laboratory of the Muséum national d'Histoire naturelle. In 1838, he became a technician or ''préparateu''r in this then, as now, famous institution. In 1841, he became assistant-naturalist. He accompanied Henri Milne-Edwards (1800—1885) and Jean Louis Armand de Quatrefages de Breau (1810—1892) to Sicily on a marine zoology expedition. He published, in 1845 a ''Histoire des insectes'', or History of the insects and, in 1854—1856 ''Zoologie agricole'' or Agricultural Zoology. This last work is remarkable: it presents in a precise way the harmful or pest species and the damage they cause to various crop plants. This work was illustrated by his father. Bl ...

Audouin's Gull
Audouin's gull (''Ichthyaetus audouinii'') is a large gull restricted to the Mediterranean and the western coast of Saharan Africa and the Iberian Peninsula. The genus name is from Ancient Greek ''ikhthus'', "fish", and ''aetos'', "eagle", and the specific ''audouinii'' and the English name are after the French naturalist Jean Victoire Audouin. It breeds on small islands colonially or alone, laying 2–3 eggs on a ground nest. As is the case with many gulls, it has traditionally been placed in the genus ''Larus''. In the late 1960s, this was one of the world's rarest gulls, with a population of only 1,000 pairs. It has established new colonies, but remains rare with a population of about 10,000 pairs. This species, unlike many large gulls, rarely scavenges, but is a specialist fish eater, and is therefore strictly coastal and pelagic. This bird will feed at night, often well out to sea, but also slowly patrols close into beaches, occasionally dangling its legs to increase drag. ...

Microsporum Audouinii
''Microsporum audouinii'' is an anthropophilic fungus in the genus ''Microsporum''. It is a type of dermatophyte that colonizes keratinized tissues (primarily hair) causing infection. The fungus is characterized by its spindle-shaped macroconidia (7–30 × 35–160 μm), clavate microconidia (2.5–3.5 × 4–7 μm) as well as its pitted or spiny external walls. Growth conditions This fungus is often found in soil that is rich in keratinous material. However, there are other factors that can influence its growth, such as pH, relative humidity, organic carbon, nitrogen and temperature. ''Microsporum audouinii'' appears to prefer a neutral pH in the range of 6.8-7.0 and room temperature for growth. Drastic increases or decreases in temperature can inhibit its growth. ''Microsporum audouinii'' is effective in utilizing its carbon sources, but growth is strongest in the hexoses (glucose, mannose and fructose) and weakest in maltose, sucrose, lactose and galactose. It is u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Gruby
David Gruby (20 August 1810 – 14 November 1898) was a Hungarian physician born in the village of Kis-Kér (now Bačko Dobro Polje, Serbia) to a Jewish farmer.Geoffrey Clough Ainsworth, ''Introduction to the History of Medical and Veterinary Mycology'', Cambridge University Press (2002), p. 13 He received his doctorate in Vienna and performed scientific research in Paris. Gruby is remembered as a pioneer in the fields of microbiology and Pathogenic fungi, medical mycology. Most of his important work was done during the 1840s, when he reported that human disease could be caused by fungi. In 1841 he described the fungus associated with favus, a discovery that was independent of Johann Lukas Schönlein's (1793–1864) findings. Later, the fungal parasite was called ''Achorion schoenleinii'' in Schönlein's honor. In 1842 he described a microscopic cryptogam (''Trichophyton ectothrix'') that is associated with a dermatology, dermatological disease known as ''sycosis barbae''. Gruby a ...

Mycologist
Mycology is the branch of biology concerned with the study of fungus, fungi, including their genetics, genetic and biochemistry, biochemical properties, their Taxonomy (biology), taxonomy and ethnomycology, their use to humans, including as a source for tinder, traditional medicine, Edible mushroom, food, and entheogens, as well as their dangers, such as poison, toxicity or fungal infection, infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around ...

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie Jules César Savigny
Marie Jules César Lelorgne de Savigny (; 5 April 1777 – 5 October 1851) was a French zoologist. Savigny was born at Provins. In 1798 he travelled to Egypt with the Emperor Napoleon as part of the French scientific expedition to that country, and contributed to the publication of the findings of the expedition in 1809 (''Description de l'Égypte''; published more fully in 1822). He wrote about the fauna in the Mediterranean Sea and the Red Sea. He is also known for proposing a theory that the mouth-parts of insects are homologous with locomotory organs (e.g. legs). Education and travel to Egypt At age 16, Savigny traveled from his home of Provins, in the department of Seine et Marne, to Paris to finish his studies. Being very interested in botany, he worked at the ''Muséum national d'histoire naturelle'' with Jean-Baptiste Lamarck and Georges Cuvier. Cuvier suggested to Napoleon that the 21-year-old Savigny should follow him as zoologist to Egypt. Savigny became responsible ...
